Specification forming part of Letters Patent No.1 87,483,7dated February20,1877, application vfiled Y Decembereo,1876.' W l To all whom it mayconcern Be it known that I, WILLIAM R. RIGHTOR, of Helena, in the countyof Phillips and State of Arkansas, have invented certain new and usefulImprovements in Pocket-Knives; .and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to .the accompanying drawings, which form partof this specification.

My invention relates to improvements in pocket-cutlery, and is designedto unite in a single knife-case, together with the usual cutting-blades,a detachable whetstone for sharpening the latter, and also a saw-blade,having a right-angular side rasping-surface.

It is frequently desirable for the cuttingblades of a knife to besharpened by honing or rubbing on a whetstone, when, or in certainplaces where, an independent and usual article of whetstone cannot beconveniently used; and my object is to provide a means whereby a stonesuitable for all practical purposes in sharpening a pocket-knife may beconstantly' carried about with the knife, and that, too, i@ such a wayas not to enlarge or render th 1 knife additionally bulky.

Referring to the drawings, Figure l is a View of a knife embodying myimprovements, with the blades exposed. Fig. 2 represents the same withthe whetstone detached. Fig. 3 is a View showing lthe saw-blade with itsfile-surfaces.

A represents the handle of the knife, made in the usual form,andfaccording to any approved style, but having one of its side pieces Aprovided with end `jaws or recesses B B', to support the independentwhetstone G,

laterally outward along the length of the handie, and affording a backsupport for the stone. This latter may be of any suitable stoneappropriate to sharpen the fine edge of a knife, and is, preferably,made with tapering or sectionally-dressed ends cc, which form tongues toengage with the end locking-recesses B B.

The drawing represents one large and two small cutting-blades, butit isevident that the number and relative size of these do not aifect myinvention, and are only shown as an example of one ot' the differentforms of construction with which my improvement may be com bined, butthe saw-blade D is a material element in my invention, and is preferablymade, as shown, large, and pivoted to the same fulcrum with the largecutting-blade of the knife. I preferably make this saw-blade of steel,since both the saw-edge, together with the rasp or filing surfaces, asare afterterward described, are best made of this ma terial, though, ifdesired, I may substitute any other metal. It has a Working-edge ofserrated teeth d, While its interior face is constructed with theraspingsurface d', sothat it may act also as a le, when desired. Theback edge of the blade, or that edge opposite to the toothed edge, isformed with a flange, E, extending at right angles out laterally fromthe handle of the knife, and constituting the fourth and adjustable sideto the entire recess F thus formed in the side piece A. Both this sidefiling-surface d of the saw-blade, and, also, the exterior edge of thisrear flange E, are rougheued, so as to present a raspingsurface at rightangles to the length of the blade, and in this manner both a wide and anarrow le are obtained, each having a rightangular working-face.

Within the seat F, made as above described, the whetstone finds secureposition, since it is bound on back and either end by fixed pieces, asdescribed, and when the saw-blade is closed the stone is locked againstdisplacement in any line of direction, the back flange E of thesaw-blade, as the latter is closed, forming the front-edge support inthis recess F, and the flange overlaps slightly the metallic end pieces,which latter have the flanges forming the end recesses B B. It isthus'apparent that the handle of the knife easily carries in one of itsside pieces the independent whetstone, instead of the bone, ivory, orother piece usually secured lxedlytherein, and that this stone can bequickly used by turning back the saw-blade, with its rear flange, andthus allowing the stone to be slid out from its supporting-seat, andused as independent of the handle.

Preferably,lmakethe remaining side pieces of the handle as is the usualmanner, the same being a xed bone piece rigidly secured in the handle,though it is obvious that I may make both sides of the handle with thedetachable stones, and not have any fixed bone or other piece securedto, and forming a part of, the knife-handle.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is y 1. A knife Whose handle is constructedwith a removable Whetstone forming part of the same, substantially asAand for the purpose described.

2. A knife provided with a saw-blade having one or more right-angularrasping-surfaces, substantially as and for the purpose described.

3. The pocket-knife constructed With one or more cutting-blades, asaw-blade, D, having rasping or filing surfaces, and a detachablewhetstone, C, the latter seated in the metallic side piece of thehandle, and substituted` Witnesses:
